Shriram Sharma
Shriram Sharma (20 September 1911 – 2 June 1990) was a social reformer, a prominent philosopher, a visionary of the New Golden Era, and founder of "All World Gayatri Pariwar", which has its headquarters at Shantikunj, Haridwar, India. He is popularly known as Pandit Shriram Sharma Acharya by the members of the Gayatri Pariwar. He pioneered the revival of spirituality and creative integration of the modern and ancient sciences and religion, relevant in the challenging circumstances of the present times. He initiated a movement for Transformation of era.

Tidal locking
Tidal locking (also called gravitational locking or captured rotation) occurs when the long-term interaction between a pair of co-orbiting astronomical bodies drives the rotation rate of at least one of them into the state where there is no more net transfer of angular momentum between this body (e.g. a planet) and its orbit around the second body (e.g. a star); this condition of "no net transfer" must be satisfied over the course of one orbit around the second body.

Variable star
A variable star is a star whose brightness as seen from Earth (its apparent magnitude) fluctuates.
